Question

The areas of two similar triangles are 81 cm² and 49 cm² respectively. Find the ratio of their corresponding heights. What is the ratio of their corresponding medians?

Answer 1

We have,
ΔABC ~ ΔPQR
Area (ΔABC) = 81 cm²,
Area (ΔPQR) = 49 cm²
And AD and PS are the altitudes
By area of similar triangle theorem

 Since, the ratio of the area of two similar triangles is equal to the ratio of the squares of the squares of their corresponding altitudes and is also equal to the squares of their corresponding medians.
Hence, ratio of altitudes = Ratio of medians = 9 : 7
